To all whom it may concern:

Be it known that we, JAMES T. ANDREW and Amnn'r W. LANDERS, citizens ofthe United States, residing at Montgomery, 1n the county of Montgomeryand State of Alabama, have invented certain new and useful Improvementsin Subsoil Plows or Cultivators; and we do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others'skilled in the art to which it appertains to make anduse the same.

0111 invention relates to improvements in subsoil plows or cultivators,and it is intended to provide an implement that will effectually stir upand loosen the soil at considerable depth below -the surface withoutactually turning thefurrow over.

Our invention will be understood by reference to the accompanyingdrawings, in which the same parts are indicated by the same referencesymbols throughout the several views.

-Figure 1 is a perspective view showing the complete instrument; Fig. 2is a detail showing the lower portion of one of the standards with thefoot thereof made detachable from the blade, the shoe being indicated indotted lines; and Fig. 3 is a detail showing the shoe detached from thefoot of the standard.

- The plow consists of the beam A, the frame 13, the handles C, thestandards D, and the shoes E, all of these parts being preferably ofmetal, except the handles C which may be of wood.

The beam A consists of a metal plate 1, to which the frame B .andhandles C are connected, as shown; the frame being formed of metal sideplates 2, flanged at each end, as at 3, and secured to the beam 1, andhaving the parallel side braces 4 to which are attached the brackets 5for bolding the standards D, to which the shoes E are attached. Thecentral standard is attached to the bracket 5 carried by the beam 1, asshown in Fig. 1. These standards D have metal shanks 6, sharpened, as at7, and terminating at the bottom in a foot 8 riveted thereto, which footis provided with the cylindrical base 9 and with the bolt hole 10. Thecutting edges-of the standards are curved, as shown in Fig. 2, to directthe feet of the standards downward, and at the same time will provide acurved cutting edge to cut through the earth, or other material, suchascorn stalks, cotton stalks, or the like.

The shoes are preferably metal castings,

such as chilled iron, or steel, and are provided with a slot 11 toreceive the portion 8 of the foot of the standard, with a groove 12 toreceive the cylindrical bottom of the standard, with a hollow forwardportion 13 to receive the toe of the standard, and with .a bolt hole 14to receive a bolt passing rangement facilitates the breaking up of theground.

It will be obvious that we provide a strong, durable and eflicientimplement for the purpose stated. It will also be obvious that variousmodifications might be made in the construction, and combination ofparts which could be used without departing from the spirit of ourinvention.

Having thus described our invention,what we claim and desire to secureby Letters Patent of the United States is 1. A subsoil cultivatorcomprising a metal beam and framework connected thereto, standardsconnected to said framework and to said beam, and provided withelongated feet, and shoes fitting said feet and detachably connected tosaid standards, the said shoes being provided with double inclined heelswith longitudinal tapering V-shaped channels in the sides thereof,substantially as described.

2. A subsoil cultivator comprising a metal beam and framework connectedthereto, standards connected to said framework and to said beam, andprovided with elongated feet with cylindrical bosses at the bottom ofsaid feet, and shoes fitting said feet and detachably connected to saidstandards, substantially as described.

3. A subsoil cultivator comprising a metal beam and framework connectedthereto, standards connected to said framework and to said beam, andprovided with elongated In testimony whereof, we our sig- 'feet withcylindrlcal bosses at the bottom natures, in presence of two' witnesses.of said feet, and shoes fitting said feet and AMES T ANDREW' detachably'connected to said standards the said shoes being provided with doublein- ALBERT LANDERS' clined heels with longitudinal tapering V-Witnesses:
